My starter since that's what all the games encourage. For Black, it's my Samurott that I raised from the most adorable starter ever, Oshawott, who I named Cye after the character from Ronin Warriors(an old classic from my childhood) whose magical samurai armor is water powered and it's even called the the "Armor of Torrent." Why couldn't he have been water/fighting so I could make really good use of how he can use special and physical attacks on a more even level compared to the other water starters?
